add support for setting proxy

[netanelgilad]

This PR adds the ability to set a proxy host and port. Setting a proxy was already available on HttpRequest, so I only added a method to expose it on the plugin interface.

Cheers 🍻

Hi Netanel, I know this was a long time ago 😥... but I'm trying to keep Android and iOS features in sync. That's the reason I've not merged this PR. Would you mind implementing it also for iOS and writing some unit tests / e2e specs? Otherwise I'll close this PR because it seems not to be requested by many users.

This would be a nice feature to have. I'm currently working with your library in a project and having to configure proxy to use the network. For now, the only way to do that is using an external app proxing all the network traffic in the device to our corporative proxy. But with some customers, it wouldn't be a viable solution.

We are studying the possibilite to use @netanelgilad 's fork in our app to be able to set the proxy dynamically.

So, if someone has the knowledge to implement the same feature for IOS, then, you can accept the PR, this feature will be a great improvement for your library!

Thanks for now!

Out of personal interest and since we have to develop behind a corporate firewall as well 👎 : Which app are you using that automatically redirects all network traffic through the proxy?
